Frank Gavin - Animal farm

They'd been stooping, holding onto the window sill as they peeked, and Rod moved his feet back on the grass so as to make his pulsing prick more accessible. He knew that his lovely sister was really steaming, as she enjoyed watching their beautiful mother being fucked, but he didn't do anything to help her out. He wanted to keep on watching the exciting erotic scene, and he knew, anyway, that Betty wouldn't hesitate about telling him if she wanted to be fucked, sucked, or fingered right then and there.

Betty quickly got his stiff cock out into the open. She wrapped her fingers around the hot shaft and stroked her hand up and down a couple of times, sliding the loose sheath of skin over the core of hard meat. Then she pushed her hand down to the base of his cock, pulling the skin back and causing his purple cock knob to pop out. She licked the swollen glans a few times and then engulfed the big knob with her mouth.

Rod gritted his teeth and tightened his grip on the window sill as the wonderful sensations of his sister's hot mouth encompassing his throbbing cockhead sent his passion soaring even higher.

Watching his mother being fucked by the handsome Mr. Anderson while his sister sucked his own cock really turned Rod on. He began making little hunching movements, pushing his prick a little deeper into Betty's greedily sucking mouth each time, and she willingly accepted more and more of the stiff shaft.

Rod hadn't been cheated in the pecker department. He was only sixteen and he already had over seven inches. And right then his fifteen-year-old sister was taking just about all of the throbbing length of cock into her mouth and down her throat. He could feel her throat muscles working around the glans each time she pushed her face forward and buried her nose in his pubic hairs.

Betty didn't know it, of course, but she was moving her sucking mouth forward and backward on his cock in practically the same rhythm as Mr. Anderson was pronging their sexy mother, Norma. He'd often thought of his sexy mother by her first name since he'd first seen her sexing it up at one of the swapping parties. He'd caught himself just in time on many occasions to keep from calling her Norma to her face during the past year or so. And Betty had mentioned that she'd had the same problem when around their father, Bill.

He guessed he'd seen his mother doing just about everything there was to do of a sexual nature with a partner or partners, female as well as male. He'd even seen her finger-fucking herself while temporarily without as partner.

At first, he'd beat his meat while peeking during the many sex parties his parents had tossed at their home. Then, after several weeks, unable to keep the secret any longer, he'd told Betty about sneaking back to the house and observing the erotic activities and acrobatics.

His sister hadn't believed him at first. And he didn't blame her. Around them their parents were straight-laced and puritanical where anything having to do with sex was concerned it was still sometimes difficult for him to believe that they were actually such sex nuts.

Rod had to believe his eyes, though, and Betty did, too. She had been the first to suggest that they should also start enjoying themselves in a sexual way. Together. She'd admitted to masturbating – and had told him that she knew damned well that he was jacking himself off after he admitted that he'd never fucked a girl.

Betty had never had sex with anybody, either, and after they'd peeked at the fucking and sucking at the sex party together she'd sucked Rod's cock. That'd really felt great, and she claimed that she'd enjoyed the experience, even if she had choked and gagged on his spurting jism.

Pulling away from his gushing cock, she'd dashed to the bathroom to wash her mouth out, and he'd had to finish himself off with his hand. Later that same night, though, she'd sucked him off again and swallowed every last drop of his semen. He'd been finger-fucking her hot pussy at the time, another exciting first for him, and he'd questioned her about her lack of a cherry. She'd laughed and said that she'd punctured that useless piece of skin with her fingers long before.

They'd tried everything during the following few days and nights, whenever they'd gotten a chance, eagerly imitating the various sexual acts they'd seen performed at the swapping parties.

The first time Rod had fucked her they'd both gone almost out of their minds, the pleasure being so sensationally thrilling. They'd both enjoyed it immensely the first time he went down on her, too. He'd discovered her clitoris while finger-fucking her and when he'd lapped and sucked that stiff and slippery passion-button she'd climaxed like crazy. She'd even learned to enjoy being corn-holed. He liked that form of fucking, but the terrific heat and tightness usually caused him to shoot off faster than he wanted to. He liked the blissful minutes leading up to the few moments of ecstatic spurting just about as much as he did the actual ejaculation.

Rod felt the tingling in his balls that meant that the jism would soon be racing through his throbbing cock and flooding Betty's mouth and throat. He glanced down and saw that she'd slipped one hand up under her dress and was frigging herself. He would've gladly performed that pleasant task – or fucked her or sucked her for that matter – but he knew that she would've told him if she'd wanted help.

He could see that Mr. Anderson was pounding faster, obviously caught up in his drive toward a spurting finish. It seemed to Rod that his wildly wriggling mother had already climaxed at least twice, but he knew that she was going for another orgasm. She had her legs wrapped around Mr. Anderson's waist and as she hunched along with each powerful thrust she clawed his back and shoulders with her hands. His finger were gripping her racing hips and their mouths were glued together in what had to be a torrid French kiss.

Rod saw Mr. Anderson tense, then shudder violently, and at the same time his own cock jerked spasmodically and sprayed Betty's tonsils with hot jism. He made little hunching movements as his sister continued to suck greedily while swallowing the thick and sticky cream she liked so very much.

His mother and the history teacher collapsed just as Betty was draining the last drop of sperm from his rapidly softening cock. She let Rod's limber dick slip from her mouth at the same time as Mr. Anderson flopped over on his back, his big cock limp and glistening under the overhead light.

Betty had pulled her finger from her cunt. Rod knew that she'd climaxed. There was enough light for him to tell that by the satisfied look on her pretty face. He helped her to her feet and accepted her passionate kiss. He'd tasted his sperm on her lips before. She pulled her mouth and tongue from his and looked in the window. He saw that their mother was swinging from the bed, a towel clutched between her legs.

"I guess Mr. Anderson really gave Mom a good fuck," Betty whispered.

"He did that," Rod said, lifting his sister's wet finger to his lips. He took the digit into his mouth and sucked, enjoying the taste of her cuntal juices. "Are you ready to go to Grandma's house?"

Before Betty could answer another couple entered the bedroom. They'd seen the man and woman before, but they didn't know their names. The woman was short and had red hair. She had big titties and look to be about twenty-five. The man was also short and looked as if he might be pushing forty. He had dark hair and his cock didn't look to be over five inches long when thrusting stiffly – as it was doing by the time they were both naked.

They didn't kiss or embrace and the woman got down on her hands and knees on the thick carpet on the floor. As the window was down, Rod and Betty couldn't hear any sounds, but that didn't detract all that much from their enjoyment. They'd both become devotees of voyeurism and they had a good idea as to what was being said – and they'd made similar sounds themselves.
